Many times I am dissappointed in the game endings. Usually because they just end abruptly. I often times have a lot of questions about parts of the story which were never answered.

I personally think the best ending to a game was in Return to Zork because the developers really wrapped up the story cleanly with no questions at the end. Also, we got to see each of the people or places where we were really stuck and spent many hours. Plus, at the time this was all very new to us. A close second would be Zork Grand Inquisitor - now THAT was a fun game!

Do you think that in the case of newer games it's because the developers are already planning a sequel to whichever game, and therefore leave a few threads hanging, or a cliffhanger? (I'm thinking specifically of Still Life and Dreamfall, both games coming up for discussion here as having unsatisfactory endings. )
